The laser range finder is an instrument for realizing distance measurement of a target by utilizing a certain parameter of modulated laser, and is divided into a phase method range finder and a pulse method range finder according to a range finding method. The pulse laser range finder emits one or a series of short pulse laser beams to the target during operation, the photoelectric element receives the laser beams reflected by the target, and the timer measures the time from the emission to the receiving of the laser beams and calculates the distance from the observer to the target. The phase method laser range finder detects a distance by detecting a phase difference that occurs when emitted light and reflected light propagate in space. Regardless of the method of ranging, the laser rangefinder is required to receive reflected light at the measurement target. In traffic engineering quality detection, there is a high possibility that there is a problem that the light reflectivity is poor or a laser reflector is absent at the measurement target, so that the length cannot be measured by using the laser range finder preferably.
